Adaptive portable libraries

ABSTRACT

Platform-agnostic source code can be augmented with one or more portions of source code annotated for different platforms and/or versions. The source code including both the platform-agnostic and platform-specific and/or version-specific portions can be compiled once to create a single executable that can be distributed to and can run on multiple device platforms and/or multiple versions of one or more platforms. Platform-specific or version-specific executables (e.g., assemblies, binaries, etc.) can be embedded into a binary or executable as resources (e.g., data). When the compiled code is executed on a device, the runtime can extract the platform-specific portion corresponding to the device on which the executable is being run, can bind the extracted portion to the executable and can load and execute the executable. Hence the same binary can produce different results or functionalities depending on the capabilities of the platform on which the binary runs.

BACKGROUND

The term “portability” as used in computer science refers to the ability to use the same software in different computing environments. The term “portable code” can be used to refer to code that is not platform-specific. That is, the very same software can run on any platform or at least on multiple platforms. The term “portable code” can also be used to refer to code that can be more cost-effectively changed to run on a different platform than writing the software from scratch. To distinguish these different usages of the same term, the term “universally portable code” will be used to refer to platform-agnostic code that can run on any platform. The term “portable code” will be used to refer to code that can be changed to run on different platforms cost-effectively.

One way to create different versions of code to run on different platforms is by conditional compilation. Conditional compilation enables the compiler to produce multiple different executables associated with multiple different platforms by compiling the code multiple times. The compiler is run with one set of parameters or directives to generate an executable for a first platform and is run with another set of parameters or directives to generate an executable for a second platform and so on.

SUMMARY

Platform-agnostic portions of source code can be augmented to include one or more portions that are annotated for different platforms and/or versions of software. The source code including both the platform-agnostic and platform-specific and/or version-specific portions can be compiled once to create a single executable that can be distributed to and can run on multiple device platforms and/or multiple versions of one or more platforms. Platform-specific attributes of a development environment can enable compilers to provide platform-specific auto-completion and type-checking Platform-specific or version-specific executables (e.g., assemblies, binaries, etc.) can be embedded into universally portable (platform-agnostic) executables as resources (e.g., data). A platform-specific abstraction layer and/or version-specific interface can also be created and can be embedded into the universally portable executable as a resource or data. The platform-specific abstraction layer can be implemented at execution time by a corresponding platform-specific executable. Development tools, for example an IDE (integrated development environment), can set up the executable so that when the executable is executed on a particular device, the executable will execute correctly. When the compiled code is executed on a device, the program execution manager (e.g., runtime) can extract the platform-specific data corresponding to the device on which the executable is being run, can bind the extracted data to the executable and can load and execute the executable. Hence the same binary can produce different results or functionalities depending on the capabilities of the platform on which the binary runs.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description.

DETAILED DESCRIPTION Overview

FIG. 1 a illustrates a system for producing universally portable code as is known in the art. Traditionally, source code with conditional compilation directives (such as source code 101) is compiled to run on a target device. For example, source code is compiled on a compiler 102 once to run on a target device such as a smartphone and produces a binary for a smartphone such as a binary for a smartphone such as binary for smartphone 104 a. Source code with different directives can be compiled a second time to produce a binary that can run on a tablet (e.g., binary for tablet 104 b). Source code with still different directives can be compiled again to produce a binary that can run on a game box (e.g., binary for game box 104 c) or desktop (e.g., binary for desktop 104 d) or other device (e.g., binary for device n 104 n). Thus the portable code is compiled multiple times to produce multiple binaries, each binary designed to run on a particular platform.

One consequence of such a design is that when software is packaged for deployment to a device, the appropriate binary has to be selected for that device. For example, the binary 104 a for the smartphone has to be deployed to a smartphone and the runtime of the smartphone 106 a will execute the binary 104 a to produce some execution result a 108 a. Similarly, the binary 104 b for the tablet has to be deployed to a tablet and the runtime of the tablet 106 b will execute the binary 104 b to produce some execution result b 108 b which may be different from execution result a 108 a. Similarly, the binary 104 c for the game box has to be deployed to a game box and the runtime of the game box 106 c will execute the binary 104 c to produce some execution result c 108 c which may be different from execution result a 108 a and different from execution result b 108 b. The binary 104 d for the desktop has to be deployed to a desktop and the runtime of the desktop 106 d will execute the binary 104 d to produce some execution result d 108 d which may be different from execution results of other devices. That is, a device-specific binary 104 n has to be deployed to the corresponding device and the runtime of that device 106 n will execute the binary 104 n to produce particular results 108 n. If the code is reused, the code has to be modified to change the device-specific portions.

FIG. 1 b illustrates a system 109 that generates a single binary (which can also be called a reference library) in accordance with aspects of the subject matter described herein. In accordance with aspects of the subject matter described herein, source code such as source code 110 can be compiled by a modified compiler 112 once to produce a single binary (e.g., binary 115) that can run on multiple target platforms. A binary as known in the art can include a code portion and a non-code portion representing resources or data. The binary 115 can include one or more portions such as version and/or platform-agnostic portion 114 that comprises version and/or platform-agnostic code and one or more portions that are version-specific and/or platform-specific (e.g., smartphone specific portion 116 a, tablet specific portion 116 b, game box specific portion 116 c, desktop specific portion 116 d or any device specific portion n 116 n). The platform-specific portions can be labeled as resources or data. The single binary 115 can be deployed to multiple different platforms.

At runtime the binary 115 can be executed by the program execution manager such as but not limited to a runtime (e.g., a runtime 118 a for the smartphone, a runtime 118 b for the tablet, a runtime 118 c for the game box, a runtime 118 d for the desktop and in general a runtime 118 n for a device n.) The runtime can extract an appropriate (matching) version-specific and/or platform-specific portion of the binary, (e.g., from the portion of the binary labeled as a resource or data) and bind the extracted version-specific and/or platform-specific portion of the binary to the version and/or platform-agnostic portion of the binary. That is for example, the runtime 118 a of a smartphone can bind the smartphone specific portion of the binary 116 a to the platform-agnostic portion 114 and can execute it to produce an execution result a 120 a for the smartphone. Similarly, the runtime 118 b of a tablet can bind the tablet specific portion of the binary 116 b to the platform-agnostic portion 114 and can execute it to produce an execution result b 120 b for the tablet. The runtime 118 c of a game box can bind the game box specific portion of the binary 116 c to the platform-agnostic portion 114 and can execute it to produce an execution result c 120 c for the game box. The runtime 118 d of a desktop can bind the desktop specific portion of the binary 116 d to the platform-agnostic portion 114 and can execute it to produce an execution result d 120 d for the desktop. Similarly, the runtime 118 n of a particular device can bind the device specific portion of the binary 116 n to the platform-agnostic portion 114 and can execute it to produce an execution result n 120 n for the device.

Likewise version-specific and/or platform-specific platform abstraction layers (not shown in FIG. 1 b) can be extracted from the data portion of the binary and can be bound to the version-specific and/or platform-agnostic portion 114. In accordance with some aspects of the subject matter described herein, the single binary 115 is produced in such a way that the one or more version-specific and/or platform-specific portions of the code are understood by the runtime as normal units of re-use (e.g., the binary is created in a format that the runtime recognizes).

Adaptive Portable Libraries

FIG. 1 c illustrates a block diagram of a system 121 that generates a single portable executable in accordance with aspects of the subject matter disclosed herein. FIG. 1 c also illustrates execution of the portable executable in accordance with aspects of the subject matter described herein. All or portions of system 121 may reside on one or more computers or computing devices such as the computers described below with respect to FIG. 3. System 121 or portions thereof may be provided as a stand-alone system or as a plug-in or add-in. System 121 may execute in whole or in part on a software development computer such as the software development computer described with respect to FIG. 4. All or portions of system 121 may be operated upon by development tools. For example, all or portions of system 121 may execute within an integrated development environment (IDE) such as for example, IDE 125, described more fully with respect to FIG. 4 or can execute outside an IDE.

System 121 may include one or more computing devices or computers such as computing device 122. Computing device 122 can include one or more processors such as processor 142, etc., a memory such as memory 144, and one or more modules such as module 123 that generate a single universally portable executable. The one or more modules represented by module 123 can comprise a part of a compilation chain 124. Module 123 can be a part of a compiler or a compiler pre-processor or a compiler post-processor or any combination thereof. It will be appreciated that one or more modules such as module 123, etc. can be loaded into memory 144 to cause one or more processors such as processor 142, etc. to perform the actions attributed to the module 123.

System 121 may include one or more other computers or computing devices including but not limited to a smartphone, a tablet, a desktop computer, a game box or any kind of computing device. Each of these computing devices may include one or more processors (not shown), a memory (not shown) and other components well-known in the arts.

A source code file such as source code file 134 may include one or more portions of platform-agnostic code such as platform-agnostic code 130. Source code file 134 may also include one or more portions of platform-specific code such as platform-specific code 132, etc. The one or more portions of platform-specific code can comprise code that is specific for running on a device such as device 1 135, device 2 137 . . . device n 139 and so on. Devices such as device 1 135, device 2 137 . . . device n 139 can include devices such as a smartphone, a tablet, a game box, a desktop computer, a laptop computer, a notebook computer or any other computing device now known or created in the future. The one or more portions of version-specific and/or platform-specific code can be annotated with identifying annotations that indicate the version and/or the type of device for which it is specific. For example, a first annotation or type of annotation can denote that the annotated section of program source code is specific for a smartphone or for a version of software for the smartphone. A second annotation or type of annotation can denote that the annotated section of program source code is specific for a tablet or for a version of software for the tablet and so on. The particular annotations used may control which compiler or version of compiler that is used to create the binary.

Module 123 may receive source code file 134 and in combination with other components of the compile chain 124 can create a single binary 129 that includes one or more portions of version-agnostice and/or platform-agnostic code such as platform-agnostic binary 126 and one or more portions of version-specific and/or platform-specific code such as, for example, platform-specific binary 128, etc. The version-specific and/or platform-specific binary 128 can include “light-up code”. Light-up code can comprise one or more features that exist in one platform or version but do not exist in another platform or version and thus “lights up” in a user interface in one platform or version but does not “light up” in a user interface for another platform or version. Version-specific and/or platform-specific binaries such as, for example, platform-specific binary 128, etc. can be designated as resources such as data associated with platform-agnostic binary 126. Module 123, etc. may also generate an abstraction layer (e.g., a platform-specific interface) for each type of platform-specific code portion encountered, based on the code associated with that platform. For example, a first platform-specific binary such as platform-specific binary 128 may be associated with a first platform-specific abstraction layer such as abstraction layer 128 a and so on. Alternatively, source code can be compiled multiple times using standard conditional compilation techniques to produce multiple platform-specific binaries that can be combined in a post-compilation operation to create a single multi-platform binary.

The same binary, e.g., binary 129 can be deployed to multiple different platforms. When the software is executed on the device to which it has been deployed, the runtime of the device (e.g., runtime 136, runtime 138 or runtime 140, etc.) can use the appropriate platform-specific binary, binding it to the platform-agnostic binary to create an executable that runs on the device. For example, suppose a platform-agnostic binary, binary A uses a platform-specific binary, binary B. At execution time, the platform-specific binary B appropriate for the device can be selected by the runtime to bind with binary A and the resulting executable can then be executed. It will be appreciated that in addition to different platforms, different versions can be similarly accommodated. The appropriate platform abstraction layer for the platform can be implemented by the runtime based on the platform-specific code selected at binding time. It will be appreciated that although described within the context of a managed language in a virtual machine environment, the concepts described herein can be applied in a native code environment. In a native code environment, platform-agnostic code can be more difficult to create.

FIG. 2 illustrates a method 200 that can create a single binary that can run on multiple different platforms. The binary can be deployed to one or more different platforms. When the binary is executed, the runtime of the device on which the binary has been deployed can determine the appropriate platform-specific binary, extract the appropriate platform-specific binary and can bind it to produce a platform-specific binary for the device. Hence the same binary can produce different results when run on different devices. The method described in FIG. 2 can be practiced by a system such as but not limited to the one described with respect to FIGS. 1 b and 1 c. While method 200 describes a series of operations that are performed in a sequence, it is to be understood that method 200 is not limited by the order of the sequence. For instance, some acts may occur in a different order than that described. In addition, an act may occur concurrently with another act. In some instances, not all acts may be performed. Moreover, it will be appreciated that although described with respect to different platforms, the operations describe below apply similarly to creation, generation, deployment and execution of different versions of software as well.

At operation 201 platform-agnostic source code can be received by a source code editor of an IDE or other software tool. At operation 202, source code that has been annotated can be received. Source code that is platform-specific can be annotated so as to identify the platform for which the source code is intended. At operation 204 the source code including both one or more platform-agnostic portions and one or more platform-specific portions can be compiled into a single binary. At operation 206 the platform-specific portions of the binary can be appended to the platform-agnostic binary labeled or designated as data or non-code resources. At operation 208 the binary can be deployed to one or more different platforms. At operation 210 the runtime of one of the devices to which the binary has been deployed can receive a request to execute the binary. The runtime can determine and extract the appropriate platform-specific portion to bind to the platform-agnostic binary. At operation 212 the extracted platform-specific portion can be bound to the platform-agnostic binary. At operation 214 the binary can be loaded and at 216 the binary can be executed.

FIG. 4 illustrates an integrated development environment (IDE) 600 and Common Language Runtime Environment 602. An IDE 600 may allow a user (e.g., developer, programmer, designer, coder, etc.) to design, code, compile, test, run, edit, debug or build a program, set of programs, web sites, web applications, and web services in a computer system. Software programs can include source code (component 610), created in one or more source code languages (e.g., Visual Basic, Visual J#, C++. C#, J#, Java Script, APL, COBOL, Pascal, Eiffel, Haskell, ML, Oberon, Perl, Python, Scheme, Smalltalk and the like). The IDE 600 may provide a native code development environment or may provide a managed code development that runs on a virtual machine or may provide a combination thereof. The IDE 600 may provide a managed code development environment using the Microsoft.NET™ framework. An intermediate language component 650 may be created from the source code component 610 and the native code component 611 using a language specific source compiler 620 using a modeling tool 652 and model store 653 and the native code component 611 (e.g., machine executable instructions) is created from the intermediate language component 650 using the intermediate language compiler 660 (e.g. just-in-time (JIT) compiler), when the application is executed. That is, when an intermediate language (IL) application is executed, it is compiled while being executed into the appropriate machine language for the platform it is being executed on, thereby making code portable across several platforms. Alternatively, in other embodiments, programs may be compiled to native code machine language (not shown) appropriate for its intended platform.

A user can create and/or edit the source code component according to known software programming techniques and the specific logical and syntactical rules associated with a particular source language via a user interface 640 and a source code editor 651 in the IDE 600. Thereafter, the source code component 610 can be compiled via a source compiler 620, whereby an intermediate language representation of the program may be created, such as assembly 630. The assembly 630 may comprise the intermediate language component 650 and metadata 642. Application designs may be able to be validated before deployment.

The various techniques described herein may be implemented in connection with hardware or software or, where appropriate, with a combination of both. Thus, the methods and apparatus described herein, or certain aspects or portions thereof, may take the form of program code (i.e., instructions) embodied in tangible media, such as floppy diskettes, CD-ROMs, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing aspects of the subject matter disclosed herein. As used herein, the term “machine-readable storage medium” shall be taken to exclude any mechanism that provides (i.e., stores and/or transmits) any form of propagated signals. In the case of program code execution on programmable computers, the computing device will generally include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. One or more programs that may utilize the creation and/or implementation of domain-specific programming models aspects, e.g., through the use of a data processing API or the like, may be implemented in a high level procedural or object oriented programming language to communicate with a computer system. However, the program(s) can be implemented in assembly or machine language, if desired. In any case, the language may be a compiled or interpreted language, and combined with hardware implementations.

Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above.
